Application September 4, 1952, Serial No. 307,795

6 Claims. (Cl. 21633) 'I'he present invention relates to devices forholding and dispensing or applying tape material and embodies, morespecifically, an improved form'of tape dispensing mechanism of suchstructure that it may be formed by simple stamping and formingoperations out of material in blank form.

In applicants co-pending applications Serial No. 297,459, tiled July 7,1952, for Tape Applicator; Serial No. 305,229, led August 19, 1952, forRoll of Tape with Cutter Blade; and Serial No. 303,587, led August 9,1952, for Pistol Grip Tape Applicator, there are described mechanism bymeans of which tape material may be conveniently dispensed or applied toa desired surface. This invention carries forward certain basic featuresof applicants above mentioned earlier inventions and incorporatestherein additional advantageous features as, for example, the structureabove alluded to by means of which the device may be formed by stampingoperations 2,723,774 Patented Nov. 15, 1955 ICC ` is shown at 10, havingtransverse cuts 11 and 12 formed and preferably in such fashion that nowaste material is produced out of the material of the blank.

A further object of this invention is to provide a device of the abovecharacter wherein the end of the tape material adjacent the severed edgeis maintained effectively against return to the roll and bent in suchfashion that the adhesive material on the tape (if the tape material isadhesive) is held so that it will not easily come accidentally intocontact with randomsurfaces but rather, held so that it may easily beapplied to a desired surface when the tape is to be again utilized.

Yet anotheradvantage of v'this invention is to provide a device of theabove character wherein the tape cutting or severing element ispositioned in a more effective location to accomplish the' desiredcutting operations.

A further object of the-invention is to provide, in cornbination withthe foregoing, a convenient holder by means of which assorted size rollsoftapes may be inserted4 and utilized to replace similar or differentsize rolls as desired.

0ther and further objects of this invention4 will Vbe apparent as theinvention is described in detail in connection with the accompanyingdrawings, wherein Figure 1 is a plan view of a blank of material out ofwhich a tape holder and dispenser is to be formed in accordance withthis invention, the fold lines being shown dotted while the lines of cutare shown in solid lines;

Figure 2 is a view in side elevation of the device formed from the blankof Figure 1;

Figure 3 is a view in end elevation looking from the left in Figure 2;

Figure 4 is a top View of the device as shown in Figures 2 and 3;

Figure 5 is a view in section, taken on line 5-5 of Figure 3, andlooking in the direction ofv the arrows, this view showing a roll oftape inserted into the holder; and

Figure 6 is a view in side elevation showing the manner in which thedevice is used to apply tape to a desired surface.

`Referring more particularly to Figure l, a blank of a therein betweenwhich a fold line 13 extends. Preferably these and other cuts are narrowslots dened by closely spaced edges 11a, 11b and edges 12a and 12b.

The blank 10 is also cut longitudinally to form slots 14 and 15 definedby closely spaced edges 14a, 14b and 15a, 15b, respectively, defining anelongated tongue 16 having an applicator head at its tip carried byyielding spring arms 16b and 16e. l

In forming the holder from the blank 10, portions 17 and 18 are bentthrough ninety degrees along fold lines 17a and 18a to assume theposition illustrated in Figures 2 to 6, inclusive, and thus become theside plates of the tape holder. In ordenthat the side plates v17 and 18may be secured effectively in this folded position, they are folded backalong lines 17b, 18b and pro vide end plate elements 19 and 20,respectively. These end plate elements 19 and 20 overlap and preferablyare shaped as shown in Figure 3, and are suitably secured to- Y getheras by a crimping operation.'

To facilitate releasably holding a roll of tape material 34 between theside plates 17 and 18 of the holder flanges 22 and 23 are foldedinwardly at lines 22a and 23a to enter the hollow core of the roll, asillustrated in Figures 5 and 6. Also, in order to relieve the sharpnessof the edges 11b, 12b, these edges may be flanged inwardly as indicatedat 11c and 12a` of Figure 4.

Coming now to the tape positioning and snubbing'struc ture of thisinvention, the left-hand end portion of the blank 10 of Figure 1 formsside linger plates 24 and 25, the entire end portion being folded backalong the fold line 13. In order that the applicator and cutting headpresently to be described may be inserted through the snubber element,the blank is cut transversely to form slot 26 defined by closely spacededges 26a, 26b and lonfor the cutter head presently to be described.

gitudinally to form slots 27 and 28. Additional transverse short cuts 29and 30 are provided to form ears 31 and 32, which are folded back alongfold lines 31a and 32a, as illustrated in Figures 2 and 5, thus toprovide a sufficiently large aperture to receive the 'applicator andsnubber head.

As will be seen from Figures l, 2, and 5, the cuts 26, 27 and 28 form atab 33 which is bent outwardly along the fold line 33a to serve as acradle orback-up member In shaping the snubber element the side fingerplates 24` and 25 are bent along fold lines 24a and 25a and, in orderthat the snubber element may flare outwardly to facilitate theapplication of finger pressure downwardly as viewed `in Figurey 6, theblank is folded along diverging lines 24b and 25h. The snubber head issecured in the desired assembled position by inserting the corners 24e,25e into slots 17e, 18C, respectively, and upsetting them on the foldlines 24d, 25d, as illustrated in Figures 2 and 5.

In order that the improved applicator and cutter head may be formed inaccordance with this invention, `the tongue is folded outwardly alongthe 'fold'line 16d and again along the lines 16e. These folds form thetwo spring arms 16e and 16b, respectively. In effecting the last namedfolds, the applicator head 16a is inserted through the aperture 3312formed by folding out the tab 33, and caused to assume the positionillustrated in Figures 2 and 5. The final form of the applicator head iseffected by folding the tongue outwardly along the aligned transversefold line 16j, inwardly along fold line 16g, and again inwardly alongthe aligned fold lines 16t, 16u. When the applicator head 16a isinserted into the aperture 331) as described, the shoulder 16k formed byfolds 16)c and 16g lodges behind snubber edge 26a so that the extendedsurface of applicator head 16a projects beyond snubber edge 26a, whichwill engage the tape as illustrated in Figure 5, to force the adhesiveside thereof against the snubber edge 26a and thus prevent the return ofthe end` of the tape toward the roll.

The cutting mechanism is formed directly upon the applicator head 16a bycutting the blank longitudinally along lines 16m, 16:1 and transverselyat 160 to form edges 16p 16g, and 16l. To facilitate the cuttingoperation the edge 16q is serrated in accordance with known procedures,and the tab 1161,4 formed by the cuts 16m,v 16n and 16o is bent backalong the fold line 16s to serve as a brace, as shown in Figures 2, 5,and 6. The head 16a is folded along the. fold line 16v to form a flange16W against which the edge 16p of the brace tab 16r rests. It will alsobe; seen that the. portions of the, applicator headin the. regions ofthe, aligned fold lines 16t and 16uv serve as projections that preventtheV cuttingedge 16g from contacting the at surface upon which the tapeis applied.

In operation, a. roll of tape 34. is insertedA into the holder byspreading the side platesv 17 and 1S and slipping the core over theflanges 22 and. 23, as shown in Figures 5. I

and 6. The end 35 is then peeled o and threaded through the aperture 33hbetween the snubbing edge 26a and the shoulder 16k of theV snubber arrn1615. In its free position the snubber arm 16b. forces the, end of thetape outwardly and downwardly (as shown in Figure 5,) to prevent theadhesive surface of the' tape from being exposed to random surfaces.

When the tape is to be applied to a desired surface, the side fingerplates 24 and 25 may be grasped between the thumb and second finger withthe roll 34 and holder generally located within the palm of the hand andwith the forenger against the upset edges 11C, 12C. By moving the tapeend- 35 against a desired surface 36 (Figure 6) and exerting sucientpressure, the, applicator surface of extension 16k causes the tape to beadhered to the surface 36. After a desired length of tape has been soadhered, the tape may be severed by turning the holdercounter-clockwise, as viewed in Figure 6, until the cutting edge 16qengages the tape, whereupon the tape is cut upon application ofcontinued pressure. By providing the cutter 16q on the movableapplicator 16 instead of on the relatively stationary portion 33, muchless movementl is required to sever the tape.

From the foregoing it will be seen that a tape holder, dispenser andapplicator have been providedv of improved form and of such structurethat they may be formed by simple operations out of a blank with nowastage of material. Moreover, the structure is such as to maintain thefree end of the tape in an unexposed position thus avoidingcontaminating it and preventing its engagement with. random surfaces.The structure is such as to maintain an effective snubbing actionagainst accidental return of the free end of the tape to the roll and,in addition, the cutting mechanism is so formed that it may be broughtinto operation effectivelyand with facility.

If desired, surfaces of the device over which the nonadhesive side ofthe tape slides may be treated with a release or antifriction agent tofacilitate they feeding of the tape from the roll as described in myco-pending application Serial No. 297,459.
